Park and static homes: newly in reach, but verify before you rely on it
Park homes and static caravans are almost tailor-made for air-to-air: they rarely have a wet central-heating system, space is tight, and a slim floor-console or wall unit heats the living space and cools it in summer — a real benefit in a metal-clad home that bakes in July. Historically, park homes struggled to access the Boiler Upgrade Scheme because they couldn't easily get a standard EPC. The April 2026 reform removed the EPC requirement from BUS, which — on the face of it — opens the door: where no EPC exists, an installer can submit alternative evidence such as a fuel bill and photos of the old heating.
The honest flag. That EPC-removal-opens-park-homes point is reported through secondary explainers rather than nailed down in a single primary Ofgem statement, so we won't present it as a certainty. If you own a park or static home, treat air-to-air BUS as 'likely eligible if residential and you're replacing your heating — but confirm with an MCS-certified installer and Ofgem before you commit'. For some park homes the more reliable funded route is ECO4 or the Warm Homes: Local Grant (both usually air-to-water and income-tested), so it's worth checking those too. Use the eligibility checker and we'll set out what applies.
Practicalities. You'll need the site owner's permission to fit the external condenser, and — as with every air-to-air home — a separate hot-water source, since air-to-air makes none.
Before you commit: the £2,500 grant only pays out through an MCS-certified air-to-air installer, and those are scarce in 2026. Air-to-air also makes no hot water, so you keep a separate hot-water source. We’ll tell you honestly if it doesn’t suit your home — no obligation, no pushy calls.

Common questions
Can a flat or park home get the air-to-air grant?
Flats: yes — air-to-air suits flats well (small outdoor unit, no cylinder or radiators needed) and BUS is open to residential properties in England and Wales; just check your lease, as a freeholder's consent for the external unit is usually needed. Park/static homes: likely eligible now the EPC requirement has been removed, but that point comes from secondary sources, so confirm with an MCS installer and Ofgem before relying on it — for some park homes ECO4 or the Warm Homes: Local Grant is the more reliable route.
